Portable Exercise Device

Field of the invention

The present invention relates to exercise devices, and in particular to portable exercise devices.

Background of the invention

When people travel, either for work or leisure, they often find it difficult to maintain a good level of fitness and strength. Whilst someone can go for a run or carry out push-ups, they are unable to carry out heavy lifting exercises (such as pull-ups) unless there is a suitable gym available.

While pull-up bars that hook onto a door frame are known, these have many disadvantages that make them unsuitable for use e.g. while travelling.

Accordingly, there is a need for new exercise devices that are easily transportable and can be used safely for example in environments that are not purpose-built for exercising.

Detailed description of the invention

Although the invention will be described by way of examples, it will be appreciated by a person skilled in the art that the invention could be modified to take many alternative forms without departing from the scope of the invention as defined in the appended claims.

Pull-up bars that fit in a doorframe, such as that shown in Figures 1a and 1b are known in the art. The pull-up bar 1 shown on Figures 1a and 1b comprises a first support member 2 that is supported on the horizontal part of the rim 4 of a doorframe, such that the device is supported by the rim 4 and extends through the door opening 14 underneath the horizontal frame 4. Attached to the support member 2 are first and second parallel spaced apart curved members 8 that extend downwardly and rearward from the support member 2 such that, in use, they pass through the door opening 14 and the ends of each curved member 8 distal from the attachment point to the support member 2 are on the opposing side of the wall 6 to the support member 2. The device further comprises a second elongate support member (or hand grip) 10 arranged perpendicular to the long axis of the parallel curved members 8 and attached to each curved member to provide, in use, a substantially horizontal hand grip portion fora user to hold. In use, the support member 10 is located on the opposite side of the wall from the support member 2 that is supported on the frame of the door. In the embodiment depicted, the second elongate support member 10 has a length along its long axis that is wider than the door opening w so that, in use, its lateral (end) portions rest against the vertical rim portions of the door frame 4. The second support member 10 may itself be used to support the weight of the user, or handles 12 in the form of extensions of the curved members 8 may be provided. In alternative embodiments (not shown), handles may be provided and extend from the second support member 10, or may loop between the second support member 10 and the curved members 8. Various parts of the device of Figure 1 a and 1 b may comprise cushioning material in order to protect the rim 4 of the doorframe and/or the wall 6.

The devices according to the prior art have many disadvantages. Firstly, the devices of the type shown in Figures 1a and 1b are large and difficult to put in place and take off. Indeed, the stability of the pull-up bar 1 requires the first and second support members 2 and 10, respectively, to be a continuous piece of sturdy material that is wide enough to provide adequate support. For example, the second support member 10 is typically at least as wide as the door frame, in order that it can rest on the frame in use. This limits the minimum size of the pull-up bar 1, as well as the minimum distance from a door frame to any wall, as the second support member 10 extends laterally beyond the frame. Additionally, this limits the use of the device to door frames that are no wider than the length of the second support member 10, as the support member 10 is supported on the door fame. Further, the pull-up bar 1 requires the presence of an upper rim 4 of the door frame that is deep enough to support the first support member 2 in a stable configuration even when in use. Furthermore, the support members frequently damage or leave marks on the door / door frame that they are fitted on, thereby making them difficult to use in situations such as hotel rooms, etc. In addition, the devices require the door to be open while exercising, as the second support member 10 rests on the opposite side of the doorframe to which the user is located, with the curved member 8 extending through the door frame. In some circumstances, such as where a door is adapted to close automatically (such as might be the case in a hotel room) this can be very inconvenient.

Pull-up handles 20 as shown on Figures 2a and b alleviate some of the drawbacks in the pull-up bars 1 of the prior art, but present other disadvantages. First and second handles 22a, 22b are each attached via a flexible strap 24a, 24b (respectively) to an elongate support member 26. The straps 24a, 24b are, in use, placed over the top edge of a door 28, such that when the door 28 is closed, the support member 26 is secured on the opposite side of the door to the handles 22a, 22b and acts as a support for the weight of the user pulling themselves up at the handles 22a, 22b. Although such systems are more portable than the pull-up bar 1, they have other drawbacks. Firstly, they put a significant downward strain on the hinges of the door.

Additionally, pull-up handles 20 of the type depicted may put the hands of the user in contact with the surface of the door 28, thereby resulting in potential injury and/or discomfort. Further, the pull-up handles 20 require the user to be very close to the door, as the handles hang down from the top of the door, thereby resulting in an unnatural and uncomfortable pull-up position as depicted in Figure 2b.

The device of the invention aims to address these and other issues associated with pull-up devices of the prior art.

Configuration

Figures 3a and 3b show schematically a device according to embodiments of the invention.

Figure 3c illustrates schematically a folded configuration of embodiments of the device of the invention when not in use.

The word “bar” is used herein interchangeably to refer to a tube, strut or rod, capable of forming a support structure as described. The bars of the invention are advantageously linear or almost linear; although curved bars whose shape does not significantly impact the transfer of forces in the device as explained below are encompassed. In particular, the bars of the invention may be curved at points of connection between attached bars, in order to avoid sharp angles or to improve the aesthetic appearance of the device.

Main frame

The device 30 comprises a hand grip in the form of a bar 32 that accommodates the hand or hands of a user, when the device is in use. The hand grip 32 is supported between first and second support struts 38, 40 (respectively), which are spaced apart and generally parallel to each other. In the depicted embodiment, the first and second support struts 38, 40 are coupled to the bar 32 at respective end portions thereof. A second bar 34 arranged substantially parallel to bar 32 and spaced apart therefrom is also coupled to the first and second support struts 38, 40 at respective end portions thereof, such that the bars 32, 34 and struts 38, 40 form a substantially rectangular frame; although the skilled person will appreciate that other quadrilateral shapes are also envisaged, such as square. In one embodiment (as depicted in Figure 3a), the second bar 34 supports a support plate 36a; and in another embodiment (as depicted in Figure 3b), the second bar 34 supports a support block 36b. The device additionally comprises a strap support bar 42, which is coupled between the struts 38, 40 and arranged substantially parallel to and between the bars 32, 34. In the depicted embodiment the strap support bar 42 is coupled on the opposing side of the struts 38, 40 to the bars 32, 34. However, the skilled person will appreciate that in other embodiments the bar 42 could be coupled on the same side of the struts 38, 40 as the bars 32, 34; or it may be arranged in the same plane as the struts 38, 40. A strap 44 is mounted onto the strap support bar 42, as described further herein below.

In the simplest embodiments, bars 32, 42 and 34 are all substantially parallel and connected by support struts 38 and 40 that are substantially perpendicular to bars 32, 42 and 34.

Although the bars 32, 34, 38, 40 and 42 are shown as separate structures that are tied, screwed, glued, soldered or otherwise fixed together, the person skilled in the art would understand that the structure may in fact comprise a single structure (e.g. a cast). Additionally, although bars 32, 34 and 42 are shown in a different plane from bars 40 and 38, the structure may in fact comprise bars that are fixed together at their extremities (e.g. forming junctions) so as to form a structure where bars 38, 40, 42 and 32 lie substantially in the same plane. In embodiments comprising a supporting block 36b, bar 34 may also lie substantially in the same plane as bars 38, 40, 42 and 32. In embodiments comprising a supporting plate 36a, the position of bar 34 is linked to the function of the supporting plate 36a, as will be explained below.

Whilst in the depicted embodiment the strap support bar 42 is arranged between the bars 32, 34 in a location along struts 38, 40 that is closer to bar 32 than to bar 34, it should also be appreciated that other arrangements are possible. Thus, in some embodiments, bar 42 may be coupled to struts 38, 40 at a location that is about equidistant between bars 32 and 34; and in other embodiments, bar 42 may be coupled to struts 38, 40 at a location that is closer to bar 34 than it is to bar 32. Beneficially, the distance between bar 32 and bar 42 may be between half of the distance between bar 42 and bar 34 and substantially the same as the distance between bar 42 and bar 34. As the person skilled in the art would understand, the minimum distance between bar 42 and bar 32 may be limited by the need to accommodate the user’s hand on bar 32; whilst force transfer benefits may be achieved when the bar 42 is closer to the hand grip bar 32 than to the plate-supporting bar 34. Advantageously, the bar 32 may have a length that is sufficient to accommodate only a single hand of a user. In such embodiments, a user may perform pull-up exercises using two separate devices of the invention, one to accommodate each hand of the user. Desirably, the two separate devices are preferably substantially identical structures, e.g. two devices such as that shown in Figures 3a or 3b. In other embodiments the bar 32 is sufficiently long to accommodate both hands of a user in an arrangement that allows pull-up exercises to be performed using only one device of the invention.

In embodiments in which the main frame (comprising bars 32, 34 and struts 38, 40) is substantially rectangular or square, bars 32, 42 and 34 (i.e. the width of the rectangle) are suitably the same length; whilst bars 38 and 40 (i.e. the length of the rectangle) are also suitably the same length. In embodiments where the device is adapted to accommodate one hand of a user, the width of the main frame may be between 15 and 30 cm long. In advantageous embodiments, the width of the rectangle is between 20 and 25 cm long. For example, in one embodiment bars 32, 42 and 34 may be about 22 cm long.

In embodiments where the device is adapted to accommodate two hands of a user, the width of the rectangle may be between 40 and 70 cm long. In advantageous embodiments, the width of the rectangle is between 50 and 65 cm long. For example, bars 32, 42 and 34 may be about 60 cm long. In some embodiments, the length of the rectangle is between 15 and 40 cm long. In advantageous embodiments, the length of the rectangle is between 25 and 35 cm long. For example, bars 38 and 40 may be about 30 cm long. In embodiments, the distance between bar 34 and bar 42 is between 15 and 25 cm. In advantageous embodiments, the distance between bars 34 and 42 is about 20 cm. As the person skilled in the art would understand, the length of the bars forming the width of the device (32, 42, 34) is limited by the need to accommodate at least one hand (or two hands, preferably at about shoulder width distance) of a user. Additionally, unnecessarily long bars may make storage and transport of the device difficult or inconvenient. Therefore, suitable length of the bars 32, 42, 34, 38 and 40 will include those that satisfy these requirements.

In embodiments, any or all of bars 32, 34, 38, 40 and 42 are made of materials such as metal, wood, polymers, or any combinations thereof. For example, any of the bars may comprise a metal core (filled or hollow) that may be partially or fully coated in a polymeric material.

In embodiments, bars 32, 34, 38, 40 and 42 may have similar or substantially identical crosssections to one another. Alternatively, bars 38 and 40 may have different cross-sections from bars 32, 34, and/or 42. In embodiments, some or all of the bars have a substantially circular cross-section. In embodiments, some or all of the bars have a square or rectangular cross section. In embodiments, each bar has a cross-section with a diameter or width / length between approx. 1 and 4 cm. As the person skilled in the art would understand, the cross-section of the bars need not be constant over the length of the bar, although it may be substantially constant in simple embodiments. In embodiments where the cross-section of some or all of the bars is not constant over the length of the bar, the minimum diameter or width I length of the cross-section is at least about 1 cm and the maximum diameter or width I length of the cross-section is at most about 6 cm.

Advantageously, bar 32 may be circular or substantially circular in order to provide a comfortable grip for the hand of a user. In embodiments, bar 32 has a shaped section adapted to accommodate the hand of a user. For example, the shaped section may comprise depressions for the fingers of a user. Bar 32 may instead or in addition comprise grooves or patterns on its surface. This may enhance the grip of the hand of the user on the bar. In embodiments, bar 32 is coated in non-slip material. For example, bar 32 may be coated in a material such as rubber. The non-slip material may itself be patterned or shaped for enhanced grip. Other bars 38, 40 and 42 of the device may have any convenient cross section, such as square, polyhedral, circular etc. Advantageously, bar 34 may have a circular cross section to allow rotation of the supporting plate 36a or block 36b around the bar 34, as described herein below.

Figure 4 illustrates schematically a device according to another embodiment of the invention. Similar reference numerals are used to describe similar structure. The device 30’ shown in Figure 4 comprises a hand grip in the form of a bar 32’ that accommodates the hand or hands of a user, when the device is in use. The device 30’ additionally comprises a second bar 34’ which supports a support block 36b’ (or which could in alternative embodiments support a support plate, not shown). The device 30’ comprises a main bar 54 that performs in this embodiment the function of the first and second support struts 38, 40 (i.e. spacing apart the hand grip from the supporting bar) and strap support bar 42. As the person skilled in the art would understand, the main bar 54 may in fact comprise multiple bars. In particular, it is envisaged that first and second support struts may be connected to the bars 32’ and 34’ at any intermediate position between that shown in the embodiments of Figures 3a-3c (in which a rectangle is formed) and that shown in the embodiment of Figure 4 (in which the separate support struts have been replaced by a single bar). Advantageously, bar 54 is substantially perpendicular to both bar 32’ and bar 34’. Bar 54 is preferably connected to bars 32’ and 34’ (directly or indirectly, see below) around their midpoint.

Depending on the configuration of the support struts I main bar, a strap support bar may be provided perpendicular to said support struts and connected thereto, or as a separate bar arranged parallel with and between the support struts. Alternatively, as depicted in Figure 4, a separate strap support bar may be omitted entirely.

In the embodiment shown on Figure 4, the device 30’ additionally comprises curved bars 50 and 52 which are connected to the bars 32’ and 34’ and the bar 54. Although curved (‘C’ I ‘U’ shaped) bars 50, 52 are shown as semi-circular bars, the person skilled in the art would understand that they can form a different shape, for example a quadrilateral shape together with the bar 32’ or 34’, respectively. Additionally, the person skilled in the art would understand that the shape of curved bars 50, 52 may not be identical. It would be apparent that the shape of bar 50 is primarily limited by the need to accommodate the hand of a user on bar 32’. In some embodiments, bar 52 may be omitted entirely, in which case bar 54 is directly connected to bar 34’ and/or the supporting block or plate, as the case may be. In some embodiments where the device is dimensioned to accommodate two hands of a user, bar 50 may be omitted entirely and bar 54 may be connected directly to bar 32’.

Other features described in relation to the embodiments of Figures 3a-3c equally apply to the embodiment of Figure 4. In particular, bar 32’, 34’, 54, 50 and 52 may be separate structures that are tied, screwed, glued, soldered or otherwise fixed together, or the structure may in fact comprise a single structure (e.g. a cast or molding).

As described above in relation to the embodiments of Figures 3a-3c, the bar 32’ may have a length that is sufficient to accommodate only a single hand of a user, and a user may perform pull-up exercises using two separate devices of the invention. In other embodiments the bar 32’ is sufficiently long to accommodate both hands of a user in an arrangement that allows pull-up exercises to be performed using only one device of the invention. As the person skilled in the art would understand, all dimensions, shapes and materials described in relation to bars 32, 34, 42, 38 and 40 are applicable to bars 32’, 34’, 50, 52 and 54.

Strap and stopper

At least one strap 44, 44’ is attached at one end to strap support bar 42 or single bar 54 of the main frame, and at the other end to a stopper 48, as seen on Figure 6c. Although Figure 6c shows an embodiment similar to Figures 3a-3c, the teaching of this figure is equally applicable to embodiments such as that of Figure 4. In use, the stopper 48 rests on the opposite side of the door from the main frame, and secures the device when the door is closed, as explained further below.

In other embodiments (not depicted), two straps 44 may be provided, which attach to respective supporting struts 38, 40. In such embodiments, the distal end of each strap 44 may each be attached to its own stopper 48, such that the device comprises two stoppers 48; alternatively both straps 44 may be attached to the same stopper 48.

In embodiments in which the device is adapted to accommodate two hands of the user (and hence the entire weight of the user), one, two or more straps 44 may be desirable to support the full weight of the user. In two-strap embodiments, the two straps 44 may be attached on bar 42 (each towards respective sides thereof), and/or at least one strap 44 may be attached on each of struts 38 and 40.

In embodiments wherein two or more straps 44 are attached to struts 38, 40, it will be appreciated that the bar 42 may be omitted from the device.

In embodiments, the strap 44, 44’ has a length of between 30 and 50 cm. In advantageous embodiments, the strap is about 40 cm long. The length of the strap is adapted to allow the device to sit securely over a door in use (as explained further below) and towards the top of the door; i.e. it should not hang so low as to be impractical for users to pull themselves up.

In embodiments, the strap 44, 44’ comprises a weaved material such as a natural or synthetic fabric, a natural material such as leather, a polymeric material, or any combinations thereof. For example, the strap may be made of nylon or tough cotton. In embodiments, the strap 44, 44’ is substantially wider than it is thick. For example, the strap may have a width of between 2 and 10 cm, and a thickness of between 1 mm and 1 cm. The dimensions and strength of the selected material of the strap should be such that the strap will not break or stretch significantly when the user’s weight is applied on the device or devices.

The stopper 48 is a piece of material that is large enough to stay on the side of the door opposite from the main frame, when the device is in use. For example, the stopper 48 may be a solid block or cylinder made of metal, wood, a polymer, or any combinations thereof. In some embodiments, the stopper may be a fully or partially hollow structure. The dimensions of the stopper 48 are sufficient to prevent it being pulled between the door and upper door frame when the door is closed and the device is in use. Whilst different sized gaps are envisaged between the top of the door and the upper door frame, typically the gap is less than about 1 cm, and so in some embodiments the stopper may have a cross section with a diameter or width I length of between about 1 and 8 cm; although smaller or larger cross sectional diameters are envisaged. The cross section of the stopper 48 may have any shape, but is conveniently circular or quadrilateral.

In some embodiments, the stopper 48 may instead comprise a hook or clip that fits over the door. For example, a simple metal bridge may be fitted over the door. In some embodiments, the strap may comprise a solid structure such as an arm. In some embodiments, the strap and stopper may together comprise a single solid structure, such as arm with a hook at the end distal from the frame, where the hook fits over the door.

Supporting plate or block

The supporting plate 36a or block 36b is attached on bar 34, 34’, and lies in contact with the door, when the device is in use, as shown on Figure 6c and described further below. The supporting plate 36a or block 36b, 36b’ is used to counteract the moment acting around the pivot point formed by bar 42 i the connection point of strap 44’ on bar 54 when in use. Indeed, as the user’s weight applies a downward force on bar 32, 32’, in the absence of the support plate 36a or block 36b, 36b’, the extremity of the device that lies proximal to the door would simply lift up and the device would lie at a disadvantageous angle to the door. Although the embodiment of Figure 4 is only shown with a supporting block 36b’, the person skilled in the art would understand that a supporting plate 36a may also be used.

In embodiments, the support plate 36a or block 36b, 36b’ is mounted to the bar 34, 34’ in such a manner as to be rotatable around said bar. In such embodiments, the supporting plate 36a can be rotated to lie substantially parallel to the support struts 38, 40, as shown on Figure 3c. In some embodiments in which a single bar 54 is present, a rotatable supporting plate 36a’ may be rotated to lie substantially parallel to bar 54 (not shown). These embodiments are advantageous for storing and transport of the device in a more compact form; but in use can take up a different angular orientation.

Advantageously, the supporting plate 36a or block 36b, 36b’ may comprise a material that creates a high level of friction with the door, in order to further decrease any movement upwards of the extremity of the structure that lies proximal to the door. The high friction material may cover the whole face of the supporting plate 36a or block 36b, 36b’ that is proximal to the door in use, or may be in the form of one or more localised sections of the said face. In embodiments, the whole supporting plate 36a or block 36b, 36b’ may be made of a high friction material. In other embodiments, the supporting plate 36a or block 36b, 36b’ may comprise a first material, such as a metal, wood or polymer, forming the body of the plate 36a or block 36b, 36b’, and a second, high friction material on the whole or part of the surface of the face of the plate 36a or block 36b, 36b’ that is proximal to the door in use. A high friction material may comprise a polymer, for example rubber, as known in the art.

In embodiments comprising a supporting plate 36a, an additional bar 46 may optionally be present, as depicted in Figures 3a and 6c. In embodiments with a frame as illustrated in Figure 4, bar 46 may be connected in the end region of curved bar 52, in a similar way as it is connected to bars 38, 40 in Figure 3a, 5a and 6c. Bar 46 acts as a stop for the rotation of the supporting plate 36a around bar 34, and provides a support point for the main frame onto the supporting plate 36a when in contact with a door in use. In embodiments comprising a supporting plate 36a, the supporting plate 36a may have a width such that it extends over the ends of the bars 40 and 38 (or over the ends of curved bar 52, as the case may be), providing a support point for the main frame onto the supporting plate 36a in use. In such embodiments, bar 46 may not be present. In embodiments in which bar 46 is present, the supporting plate 36a may have a width such that it does not extend over the ends of the bars 40 and 38 (or over the ends of curved bar 52, as the case may be). In embodiments, bar 46 is made of metal, wood, a polymer, or any combinations thereof. Bar 46 may have any shape of cross-section such as a circle, quadrilateral, hexagon, etc. Bar 46 may have a cross-section with a diameter or width / length of between about 0.3 and 4 cm. Advantageously, bar 46 has a cross-section with a diameter or width I length of about 1 cm.

In some embodiments the supporting plate 36a may be mounted on bar 34, 34’ such that it is not rotatable around the bar 34, 34’, for example, when bar 34, 34’ is integral to the supporting plate 36a. In such embodiments it will be appreciated that bar 46 may not then be present. In embodiments, the supporting plate 36a is a substantially rectangular or square plate. In embodiments where the device is adapted to accommodate a single hand of a user, the supporting plate 36a may have a width of between about 8 and 30 cm (where the width is used here to refer to the dimension that aligns with the width of the main frame, i.e. the dimension that is parallel to bar 34). In some embodiments where the device is adapted to accommodate a single hand of a user and a bar 46 is present, the supporting plate may have a width of between about 8 and 20 cm. In embodiments, the supporting plate 36a may have a length of between about 5 and 30 cm (where the length is used here to refer to the dimension that is perpendicular to the width). For example, in some embodiments, the supporting plate 36a has a width of about 10 to 15 cm and a length of about 15 to 25 cm. In embodiments where the device is adapted to accommodate two hands of the user, multiple separate supporting plates 36a may be provided along the length of the bar 34, 34’. The multiple separate supporting plates 36a may have dimensions similar to those specified above in relation to embodiments of the device adapted to accommodate a single hand of a user. Alternatively, a single supporting plate 36a may be provided. In such embodiments, the supporting plate 36a may have a width of between about 30 and 70 cm. In these embodiments, the supporting plate may have a length of between about 5 and 30 cm. In some embodiments where the device is adapted to accommodate two hands of a user and a bar 46 is present, the supporting plate may have a width of between 30 and 50 cm. For example, the supporting plate may have a width of about 40 to 50 cm and a length of about 15 to 25 cm. In embodiments, the supporting plate 36a has a thickness of between 0.2 and 2 cm, for example about 0.5 to 1 cm.

In embodiments, the supporting block 36b, 36b’ may be a substantially rectangular cuboid block, as shown in Figure 3b. In some embodiments, the block has a substantially square or rectangular cross-section. In embodiments, the width of the block (where the width refers to the dimension along the same axis as for the supporting plate 36a, i.e. the axis that is parallel to supporting bar 34, 34’) is between about 8 and 20 cm (e.g. where the device is adapted to accommodate a single hand of a user, or where the device is adapted to accommodate two hands of the user and multiple (e.g. two) blocks are present along the width of bar 34, 34’), or between about 30 and 50 cm (e.g. where the device is adapted to accommodate two hands of a user and a single block is present along the width of bar 34, 34’). In embodiments, the length of the block (where the length refers to the dimension along the same axis as for the supporting plate) is between about 5 and 15 cm. In embodiments, the block 36b, 36b’ has a depth (dimension along the third axis, referred to as “thickness” for the plate 36a) of between about 3 and 15 cm, for example about 5 cm. The block 36b, 36b’ may be mounted to bar 34 by any suitable means. Conveniently, the block may comprise a suitably dimensioned through bore 361 to receive the bar 34 of circular cross section, as shown on Figure 3b. In this embodiment the supporting block 36b is depicted as being solid other than for the bore 361. In some embodiments, the bore 361 may be located slightly off the centre of the cross section of the block, in order to naturally rotate around bar 34, 34’ in use. It will be appreciated, however, that the block 36b, 36b’ need not be solid and may be at least partially hollow. Additionally, the block 36b, 36b’ may be attached to I mounted on the bar 34, 34’ by any suitable means. As mentioned above, the supporting block 36b, 36b’ may be mounted to the bar 34, 34’ in such a manner as to be fixed, or it may be mounted to the bar 34, 34’ in such a manner as to be rotatable around said bar.

It should also be appreciated that other structures to a support plate 36a or block 36b, 36b’ may be used, provided such structure is capable of transferring force between the main frame 32, 34; 38, 40 or 32’, 54, 34’ and a door, in use, whilst avoiding the device becoming unstable. For example, in its simplest form, the surface of the device 30, 30’ that lies adjacent the door face, in use, may be shaped to provide a support surface: for example, the support surface may be provided by the ends of struts 38, 40 or 52 and the side of bar 34 or 34’.

Palm-to-palm full ups

Figure 5a shows schematically an embodiment of the invention wherein an additional structure 56 is provided between bars 32 and 42, in order to allow for palm-to-palm pull ups. Figures 5b,

5c and 5d show schematically alternative configurations of the structure 56 for palm-to-palm pull ups. In the simplest embodiment shown on Figure 5c, the structure for palm-to-palm pull ups 56 is in the form of a substantially straight bar. Beneficially, bar 56 is substantially perpendicular to bars 32 and 42. Advantageously, bar 56 is connected directly or indirectly to bars 32 and 42 around the midpoint of these bars. As the person skilled in the art would understand, all features specified in relation to the shape and material of the hand grip section of bar 32 are similarly applicable to bar 56. In some embodiments, the structure 56 additionally comprises one or more curved bars (wishbone structures) 56a, 56b. Advantageously, curved bar 56a connects the structure 56 on either side of the strap connection point on bar 42. Advantageously, curved bar 56b is configured so as to allow enough space for a user’s hand to grip bar 32. For example, in embodiments where bar 32 is dimensioned to accommodate a single hand of a user, curved bar 56b may connect bar 42 so as to allow enough space for the user’s hand to grip bar 32 between the connection points. In some embodiments where the device is dimensioned to accommodate two hands of a user, two structures 56 may be present. In such embodiments, curved bar 56b of each of the structures 56 may connect bar 42 in such a way as to accommodate a hand of a user between the connection points of each curved bar 56b, or on one or either side of the connection points of each curved bar 56b.

As the person skilled in the art would understand, in embodiments where the structure 56 does not comprise a curved bar 56a, two straps 44 may be provided that are connected to bar 42 on either side of the bar 56, or on bars 38 and 40.

Devices in use

Figures 6a, 6b and 6c show schematically devices according to embodiments of the invention in use.

Figure 6a depicts an embodiment where two devices 30 each adapted to accommodate a single hand of a user are used. In this embodiment, the devices 30 comprise a supporting plate 36a.

Figure 6b shows an embodiment of the invention comprising a supporting plate 36a, where the device 30 is adapted to accommodate two hands of the user.

Figure 6c shows schematically the device of Figures 6a or 6b seen from the side.

As mentioned above, the device 30, 30’ of the invention can be easily installed onto any type of door or similar structure. Thus, in use, the strap 44, 44’ is placed over the top of the door such that the stopper 48 is on the opposite side of the door to the main frame 32, 34, 38, 40, or 32’, 34’, 54 and the door is closed trapping the stopper between the top of the door and the upper door frame when the main frame 32, 34, 38, 40 or 32’, 34’, 54 is pulled downwards, and the support plate 36a or block 36b, 36b’ is positioned so as to rest against the surface of the door.

In use, the user holds bar 32, 32’, and the user’s weight is transferred to the door through a combination of the supporting plate 36a or block 36b, 36b’ (via the main frame) and the strap 44, 44’ and stopper 48. The weight of the user W will cause a horizontal force and a vertical force, because of the angle between the strap and the door. As each of these forces is smaller than the simple vertical force associated with the user, the vertical downward force of the user that is exerted onto the hinges of the door is beneficially reduced compared to e.g. the pull up handles of Figure 2. In embodiments, the angle between the strap and the door may be between about 25° and 40°, for example about 30° to 35°. As the person skilled in the art would understand, the angle may depend on e.g. the location where the user places the supporting plate 36a or block 36b, 36b’, and the length of the strap 44, 44’.

Furthermore, the shape and structure of the frame 32, 34, 38, 40 or 32’, 34’, 54 is such that the user is located away from the closed door, thereby allowing a comfortable and stable pull-up position.

When not in use, the device can be simply and efficiently stored as the strap and plate (if present) can be folded onto the device.

Many modifications may be made to the above examples without departing from the scope of the present invention as defined in the accompanying claims.
